Title: Apparatus for extraction or fractionation of various solutes
IPC: B01D11/04
Filed: 1953-05-28
Abstract: 760,921. Extraction, &c. processes. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE'. May 28, 1953 [May 29, 1952], No. 14911/53. Class 81(1) Apparatus for bringing into contact with each other two substantially immiscible liquids of different densities for extraction, &c. comprises a series of closed vessels, at least one of the end vessels being supplied with one of the liquids under pressure, whilst the other end vessel is provided with an outlet orifice, the opening of the outlet orifice of one of the end vessels causing any source which opens into this vessel to be put out of action as well as closing any outlet orifice in the other end vessel, and conversely, the bottom end of each vessel communicating with the top of the next vessel through orifices such that they produce a gradual diminution in pressure from the first to the last vessel, and in each vessel, a dispersion of the mobile phase in the stationary phase followed by a stratification by gravity. Each vessel may comprise a cylindrical glass tube closed at the end with metal discs with plastic joint rings. The discs are either pierced with small holes, or the holes may be fromed in ruby, glass or metallic carbide inserts. In Fig. 1, vessel 6 contains a light liquid, say, the extracting phase, and vessel 8 a heavy liquid, say, containing the solute to be extracted. The liquids are transferred by means of compressed air lines 10. The units 1 are first filled with pure solvents so that the interface is at the middle of each unit. Thereupon, the heavy phase is passed down the column, the light solvent in the top unit becoming progressively richer in solute up to saturation. When say five out of twenty five units have reached this concentration, an automatic valve timer shuts off feed from 8 (via valve 11) and admits solvent from 6 (via valve 13), to discharge the saturated light solvent. Another construction is shown in which two columns of extraction units are employed.

Title: Improvements in relating to the working up of ores and other materials containing zinc oxide mixed with the oxides of volatile metals, such as lead
IPC: C22B19/02
Filed: 1935-05-22
Abstract: Ores and other materials containing zinc oxide mixed with the oxides of volatile metals such as lead are treated to obtain zinc oxide by converting the contaminating oxides to sulphides and sintering until clinkers are formed, the sulphiding and clinkering processes being effected during a single passage through the furnace.  Zinc blende may constitute the sulphiding agent, and the process may be carried out in a rotary furnace operated at 920--990 DEG  C. with a reducing flame, whereby the sulphides formed are volatilized and separated from the zinc oxide.  The Specification as open to inspection under Sect. 91 comprises also the following subject-matter: the process may be carried out in an intermittently operated short rotary furnace firstly to volatilize and recover lead sulphide at 900 DEG  C., secondly to form clinkers of zinc oxide at an increased temperature, say at 1050 to 1350 DEG  C., using an oxidizing flame, and lastly with an addition of coke to reduce and volatilize zinc which is burnt to oxide and recovered; the conversion of the lead oxide to sulphide may be effected, say at 850--950 DEG  C. without volatilizing it, or lead arsenide may be formed, and separation of the zinc oxide from sulphides may be effected by floatation; and iron pyrites or sulphuric acid and coke may be used as sulphiding agents.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the treatment of cereals prior to flour milling
IPC: A23L7/10
Filed: 1940-10-08
Abstract: 544,360. Treating grain. ROGERS, J. H., ROGERS, F. H., and HUZENLAUB, E. G. Oct. 8, 1940, No. 15014. [Class 58] A process for enriching grain consists in (a) steeping the grain with or without pressure in warm water or in warm solution obtained by a previous steeping of grain or grain offals, whereby is obtained a solution rich in vitamin and salts extracted from the grain, the steeping being carried to such. an extent that the grain absorbs at least sufficient water to bring the grain to the condition in which its rate of absorbency is at its maximum, (b) withdrawing the residual enriched solution, (c) drying the grain, (d) during the process of drying and when the content of water in the grain is such that the rate of absorbency is at its maximum, redamping the grain with the solution for a short period as by spraying, and (e) completing the drying operation. Before steeping, the grain may be de-aerated. The grain may first be partly milled, a solution of vitamin and salts prepared from the offals thereof being used for steeping and redamping the partly milled grain. It is stated that the maximum rate of absorption of water appears in most cereals to exist when the grain contains between 18 and 38 per cent. of water. The drying may be effected in a steam-heated vacuum dryer. The pH value of the steeping solution may be maintained on the acid side-say, pH5. After withdrawal of the solution from the grain the solution may be filtered and treated with deodourizing and bactericidal agents-e.g. activated charcoal, may be supplemented by water, additional extract, Vitamin B, extract or soluble mineral matter, and may be used for treating further batches of grain. After steeping, the cereal-e.g. rice-may be damped by low pressure steam and parboiled.

Filed: 1956-05-17
Abstract: 816,833. Tyre moulding presses. McNEIL MACHINE & ENGINEERING CO. May 17, 1956 [Aug. 2, 1955], No. 15375/56. Class 87(2). Tyres are removed from a press by two arms, one on either side of the press, arranged to support and lift the tyre, with means to move one arm above the other causing the tyre to tilt and slide out of the press. In the form shown one arm 64, pivotted at 70, is connected by a link 55 to a crank 44 which is pivoted at 46 on a stanchion 40 and is moved by a piston 50 and cylinder 60 which are pivotally mounted at 77 on a second crank 72 which is pivoted at 85 on the stanchion 40. The crank 44 is connected to the other arm 15, which is pivoted at 12 on a stanchion 11, by links 36, 27 and a bell crank 34. The paths of movement of the tyre lifting ends of both arms are shown by chain dotted lines. In operation, the press opens and the tyre is elevated by the diaphragm 5. Pressure admitted to the top of the cylinder 60 forces the piston 50 to move down, and so causes the crank 44 to move about the pivot 46 and thus the arms 64, 15 to move from their idle position to an horizontal position, partially stripping the tyre from the diaphragm. The arms then pause sufficiently to allow the diaphragm to be fully stripped from the tyre by the press, further movement of the piston 50 and crank 44 being prevented by a stop 57. The supply of further pressure to the cylinder 60 then causes the latter to move upwardly, pivoting the crank assembly 72 about 85 and so causing the arm 64 to continue its movement, tilting the tyre until it slides by gravity out of the press onto a roller 21, carried by the arm 15, and then to a conveyer for removal. The arms 15, 64 are L-shaped. The arm 64 is rotatably mounted in a carrier 62 so that it can be turned to give access to the lower mould section for changing. Pairs of arms 15, 64 may be pivoted at 12 and 70 for lifting types from two mould members.

Patent GB-634801-A (GB)
Title: Improvements in or relating to the manufacture of trichloriminocyanuric acid
Filed: 1947-06-12
Abstract: Trichloriminocyanuric acid is prepared by passing a stream of chlorine, while being activated by light radiation, over a cooled flowing film of a solution of cyanuric acid in aqueous caustic alkali.  Preferably, the solution flows down the outer surface of a water-cooled tube which is surrounded by an outer tube through which the irradiated chlorine passes.  The yield is improved by subjecting the solution to a preliminary chlorination by passing chlorine through the solution.  The chlorine may flow at a rate at least six times the theoretical rate.  The annular space through which the chlorine flows may be irradiated with light sources consisting of ordinary gas-filled bulbs, strip-lights and an ultra-violet lamp.
